An imaging apparatus includes a solid state imaging device in which pixels are arranged in a matrix. Row transfer lines and column transfer lines are each sequentially scanned so that video signals are delivered time-serially from the respective pixels to an output terminal. The row transfer lines are selected by a CTD which is scanned by drive pulses to sequentially and cyclically transfer charges therethrough. Gates associated with the CTD select one of the row transfer lines at a time responsive to a potential which is developed by the charges. The column transfer lines are selected by a shift register which addresses selection gates associated with the respective columns one after another responsive to a clock. The CTD may be assigned to the column transfer lines and the shift register to the row transfer lines. The apparatus is applicable even to a solid state photosensor arrangement made up of an array of photosensor elements in which case only one of the row transfer lines will be used.
